Need help regarding query string in asp.net

Question

I have a page create-quote.aspx. I want to open this page in different modes, depending on whether a querystring parameter is present or not.

My question is at which event should I check, If I have a querystring parameter or not. I think, it should be preinit, what do you say.

Answer 1

Probably the best choice is to handle them on Page_Load event:
